Here are some of the compliments we have received from satisfied patients.  We enjoy hearing from our patients and always strive to provide excellent service and care.
The exam and surgery process was so smooth and the office is very organized. I would definitely recommend Dr. Yoon to my friends.

Judy Howard

I am a 75 year old retired teacher and coach. I enjoy walking my golden retriever, fishing, working in my yard and spending time with my 2 granddaughters. I encountered Dr. Yoon when I found out I had cataracts. Dr. Yoon and his staff are friendly, courteous, very competent and completely professional. I would not hesitate to recommend him to my friends and family. In fact, I already have!

Charles Fletcher

Dr. Yoon, Dr. Thakrar and their staff made this whole surgery process easy and comfortable. I have worn glasses my entire life, but since my cataract surgery I can now get by with just reading glasses and it's feels wonderful!


I have been wearing glasses since I was 5 years old. Over the years, I have had to get larger and larger televisions to account for my decreased vision. Now that I had my cataract removed I can actually see what's on the Tv!

Doris Edenburn

I didn't realize how fuzzy my vision had really gotten from the cataracts and I was beginning to have difficulty driving at night. Now that I have had both of my cataracts removed I just can't believe how clear my sight is. I am so pleased with the results.

Judy Powers

The care at this office has been outstanding. I always get in for my appointments quickly but never feel rushed by the Doctors or staff.

Vivian, cataract surgery patient.

The day after the surgery is like Christmas morning. Your vision is amazing just overnight. It even gets a little better throughout the week. You find yourself staring at everything that you couldn't see before. This surgery is one of the best things I've ever done. Truly a gift!!!

Lisa Wright

Thank you for allowing me the opportunity to share my recent experience with Rockford Eye & Laser Center. My name is Melissa, and I am a Training Developer and Facilitator for Landstar. I have worn glasses most of my life because my eyes were too sensitive to wear contacts. This made most of life's enjoyable aspects a chore. I am a very active person and trying to swim, dance, and workout without my glasses was a pain.

I began to be intrigued about LASIK surgery about five years ago. After doing a lot of research and meeting many local doctors, I chose Dr. Yoon. I found him to be humble, yet extremely professional and thorough. My initial consultation was free, and the ladies in the office provided me with star treatment. From the moment you walk into the office, you have a warm feeling. The ladies quickly learn your name - so you are not just a number- yet an important client. The great news was - I was a candidate for this procedure! I was elated!

Two weeks later and after another appointment - I had my procedure. I was amazed at the fact that it was painless - I was extremely nervous because I do not like anyone touching my eyes. By the time I walked into the room for my procedure - I was calm, relaxed, and ready!

The results were immediate!! I remember crying to my husband that night at how amazing I felt. For the first time I could see my husband's and children's faces - glasses free (you can't put a price on that)! I now see 20/15, and I wish I would have had the procedure earlier!

Thank you Dr. Yoon and staff for your compassion, professionalism and treating me like a person.

Melissa Gelafio

Thank you to Dr. Yoon and his entire staff. Everyone is so warm, friendly and makes you feel at home. I've had horrible vision from the time I was in grade school, so I was worried my vision would not be able to be fully corrected. Thanks to Dr. Yoon and his entire staff, I now see better than 20/20. I can't even describe how happy this makes me to be liberated from the hassles of contacts and glasses. I couldn't imagine going anywhere else, everything was perfect.

John Pody

Lasik surgery was the best decision I ever made. I decided to do only my left eye and leave my right eye alone. I now have 20/15 in my left eye, which I use for distance, and use my right eye for reading. It has been 7 months since my laser surgery was done, and I would do it again.


This is by far the best money I’ve ever spent, and I would definitely recommend Dr. Yoon, along with his entire staff, to anyone considering LASIK surgery. They are all extremely professional, and very understanding of the concerns their patients have. Everyone at this office pays extreme attention to detail (from Amber at the front desk greeting me with a smile every time and remembering who I was, to Dr. Morfoot taking the extra time necessary to answer the barrage of questions I had, to Dr. Yoon talking to me through the procedure to inform me of what's happening)... Something that’s rarely found these days!

The entire procedure was explained to me in very fine detail, and the staff made certain that I was comfortable prior to getting started. I was amazed that it took as little time as it did for the procedure to be completed. Had I known it was going to be that easy, I would have done it years ago!

Having worn glasses for 20 years, I was somewhat skeptical that a LASIK procedure would fix my eyes to the level I wanted – 20/20. Not only did they reach 20/20 with the wavefront technology, but they surpassed it by getting my vision all the way to 20/15 (and it's still getting better a week after surgery)… Far superior to any vision I’ve ever had before, even with glasses!

To Dr. Yoon and his staff - Thank you for allowing me to finally see the world in HD without glasses or contacts! This is amazing!

Wes Moseley

Having this surgery has completely changed my everyday living. I have two small children, and I love that when they get up in the middle of the night, I no longer have to try and find my glasses. Also getting ready in the morning is so much faster not having to clean contacts and put them in.

Julie Ruiz

Dr. Yoon is an excellent eye surgeon with extensive experience. As a physician, I appreciated his MIT engineering background. I rely on my eyes, and I couldn't be happier with the result.

Steven Mull, M.D.

I have to admit at first I was a little scared to have the LASIK procedure. I waited almost a year to have my LASIK consult while researching on the internet and reading about other's great results. When I finally went for my consult-work-up, I met with Dr. Morfoot. She was very helpful in explaining what to expect from the LASIK procedure. She was very informative and even made me laugh at one point. She also did very well with my eleven month old daughter who was not as patient as I might have liked. Once I had weighed my options given to me by Dr. Morfoot, I scheduled my surgery.

I came in the day of my surgery and met with Dr. Yoon. He was also very knowledgeable. Dr. Yoon double and triple checked all the data and calculated the laser for my specific needs. Also, during this time I met with all the wonderful staff at Rockford Eye and Laser Center. They also were very knowledgeable about the procedure and knew exactly how to prepare me for the surgery.

Once I was medicated, I was ready for surgery. I was taken to the operating room where the laser was kept. During the procedure I was given quite a few clear directions by the doctor and two operators. The procedure itself although slightly uncomfortable, was not painful. After the surgery was complete, I was asked to sit up and walk to a waiting room. Much to my surprise, I saw better than I had seen in ten years and it was only 30 seconds after the procedure!

After waiting in the dark room for 20 minutes, I was then seen by Dr. Yoon one final time. I was released home to recover from my surgery. At first it seemed as though I was underwater with my vision fluctuating from good to worse. The rest of the day I was very excited to see my vision getting better and better throughout the day. The next morning I woke up and was seeing better than I could even with my contacts or glasses before! This was also confirmed when I went to my follow-up visit the next day.

I want to personally thank the staff at Rockford Eye and Laser Center for correcting my vision. I no longer have to hassle with contacts in the morning and before bed. I no longer have to continually clean my glasses so I do not have grease spots obstructing my view. I no longer have headaches that have plagued me since college from wearing my glasses. Yet even better, I have sharper vision than I knew was possible!

Ryan Scott

Dr. Yoon did my Laser Vision Correction. I am very happy and have not had any problems. I really enjoy not having to wear glasses all the time. The procedure was explained to me thoroughly which made me feel at ease going into it. Dr. Yoon and his staff were very nice and patient. Thank you for helping me see better than ever! I would recommend it to everyone who is tired of wearing glasses and trying constantly to keep them clean, especially if you work outside.

Russ Buchanan

I was a little nervous about the procedure itself, but was so surprised and relieved that it was really painless and quick. Just like the doctor said it would be! As soon as I walked out of the procedure room, I could see right away and was amazed! I wish I would have had laser vision correction a long time ago. I am very happy with the procedure, recovery time, and how thorough and professional Dr. Yoon and his staff were. I would definitely recommend him and his staff to anyone seeking laser vision correction!

Jovita Donahue

The surgery went great. There was no pain and about 4 hours later I looked at the TV and could see it. It was great, I would do it all again in a heartbeat. The staff was very nice and helpful. It is a great office and with friendly people. Thanks.

Hollie Huling

PRK has enabled me to simply have no worries about my vision. Now, rather than scrambling around in the morning to find my glasses or worry about the uncomfortableness of wearing contacts, I can simply get up, get ready, and go. I have never been able to see as clearly, even with glasses, until having PRK. Having this procedure has definitely changed my life for the better and I would recommend Dr. Yoon to everyone who is interested! Thank you Dr. Yoon!

Aya Sato

It's been a great improvement to my quality of life. I have an active fitness regimin and would never wear contacts or glasses during my workouts. It's wonderful to actually see clearly while running, just waking or at any time without contacts. My eyes feel better and even look clearer. I would highly recommend the procedure.

K. Baumgartner

I got Lasik surgery 6 months ago and it was the best decision of my life. No more dealing with contacts or glasses. It's an amazing thing. Dr. Yoon was incredible. Not only does he take the time to get to know you and your eyes, but he also has a great personality that makes you feel very comfortable and safe. I recommend both Lasik eye surgery and Dr. Yoon to everyone who has problems with their eyes.

Holly Dinges

My PRK experience was great! I've worn glasses/contacts for 14 years and this surgery was one of the best things I've ever done for myself. The staff is helpful and professional and did a great job of answering my question and helping me decide which options were best for me. The only negative side effect that I've experienced is that my friends all think I'm ridiculous because I'm constantly reading far away objects!


It's nice waking up with clear vision. I feel my quality of life has significantly improved since getting laser vision. Dr. Yoon is an excellent physician.

Dr. Jason So

Exceptionally happy with my newly acquired vision! Lasik has made my morning routine less of a chore and I'll never have to worry about losing my glasses or having my contacts fall out. Such a great feeling!


I am very pleased. Very professional and courteous. Great one on one consultations. I felt I was in great hands before, during, and after. Thank you!


The procedure was quick, easy and relatively painless. I can drive without glasses or contacts and can finally fall asleep without worrying about taking my contacts out.

Barry Doetch

My experience was wonderful. Dr. Yoon and his staff made sure that I was comfortable at all times. Everything was accomplished in a professional and timely manner. I would recommend it to anyone. In all of my 28 years, I do not think my vision has ever been this good. Thank you Dr. Yoon and your wonderful staff!

Rachael Williams

It was an amazing experience, and I am so glad I chose to do Lasik. The staff was very helpful and friendly. I really felt comfortable. Every step of the procedure is explained to you before hand so there are no suprises. I couldn't be happier!

Leina Luelf

My Lasik was the best thing I have done! It was amazing to see 20/20 the day after surgery and no pain! Would highly recommend to friends and family. Thank you to Dr. Yoon and staff. My experience was wonderful!

Stacy Young

I have struggled with glasses and contact lenses since I was in 7th grade. I always disliked wearing glasses and a couple of years ago I became unable to wear contact lenses. Having to wear glasses all the time became very bothersome so I decided to look into Lasik surgery. What Dr. Yoon and his staff have done for me is a dream come true. I am now seeing perfectly. It is great to wake up and not have to look for my glasses, worry about cleaning them multiple times per day, etc. I am a very active person and spend a lot of time outdoors. Just being able to wear sunglasses is awesome. No more headaches from squinting all day. The whole procedure was totally painless and having Lasik was one of the best decisions I have ever made.

Scott Klarer

This has been an awesome experience for me; the only regret I have is that I waited so long to get it done. I am an outdoors person; I love nature, hiking, biking, canoeing etc. To be able to not worry about the wind blowing something under my contacts or just to be able to “see” the dragonflies dancing has been incredible. I am also thrilled with the decision to do the monovision, being able to see when I look up from a book without adjusting the readers yeah! No more cleaning solutions, spare contacts, case, glasses, packing for vacation or an overnight trip will be so much easier. Easiest way to describe it, “freedom”.

Alice R. Vulgamott

I had PRK done about a month ago. I was very hesitant at first because I felt I was doing something that could possibly affect my life permanently. However, Dr. Yoon and his staff were very knowledgeable and that made me feel most comfortable. We had a roadblock in that we could not do Lasik due to the shape of my eye. I felt confident that Dr. Yoon was taking all precautions necessary to keep my health at the utmost importance, by not doing Lasik. Instead we chose PRK. The process of PRK made me nervous but I went ahead. I believe there was more recovery than Lasik but the possible side effects were supposed to be lower. In retrospect I’m happy I did PRK. I haven’t had any complications, no halos, no dry eyes, and 20/20 vision. (Possibly better!) Rockford Eye and Laser Center did everything perfectly. There were no unexpected negative surprises. The entire process couldn’t have gone any better. Thanks for everything!

Addison Jun

I had a great experience with the staff at Rockford Eye and Laser Center. They answered all of my questions prior to surgery and helped make the procedure as comfortable as possible. The procedure was quick with minimal discomfort. I am 100% satisfied and very pleased I decided to go through with Lasik. It has already benefited several aspects of my life including playing sports, wearing sunglasses, and working at a computer. I would suggest going to Rockford Eye and Laser Center to anyone interested in Lasik eye surgery.

Jonathon Gasteiner

I just got my LASIK done last week and love not having to wear glasses or contacts. Dr. Yoon and his staff are always very nice and only wanted the surgery to be successful. They do lots of tests and educate you on the process, which was helpful. I chose Dr. Yoon over other places because they seemed honest, did more one on one with you, and truly wanted to improve and help your vision and overall life. I am happy with the results and thank Rockford Eye and Laser and Dr. Yoon for everything!
